HAY ELEVATOR AND STACKER.

EPECIPICATION forming part of Letters Patent No. 374,787,6lated December13, 1887.

Application filed August 15, 1887. Serial No. 246,961. (No model.)

To aZZ whom it may concern:

Be itknown that I, PETER F. FLEMING, a citizen of theUnited States,residingat Huntsville, in the county of Randolph and State of Missouri,have invented certain newand useful Improvements in Hay Elevators andStackers; and I do'hereby declare that the following is a full, clear,and exact description of the same,reference being bad to the annexeddrawings, making a partoft-his specification, and to the letters ofreference marked thereon.

Figure 1 of the drawings is a perspective View of my improvedhay-elevator; Fig. 2, a top plan view of that portion of the elevatorused in grabbing the hay; Fig. 3, a sideelevation thereof, and Fig. 4 adetail view of the upper end of the derrick-post and its attachments.

The present invention has relation to devices for elevating hay andother loose substance and depositingit on ahay-stack, wagon, or otherconvenient place, and is especially designed as an improvement on myformer patent of January 13, 1885, No. 310,810; and the inventionconsists in the several details of constructions, substantially as shownin the drawings, and hereinafter described and claimed.

In the accompanying drawings the derrick or main frame of the machineconsists, in part, of the short upright post A, to the lower end ofwhich is suitably connected a cross-head, B, provided at its ends withrunners a, and at or near its center with runners b, to facilitatemoving the machine or device. Between the runners b are secured theinner ends of supporting-beams c, strengthened by braces d, attached atone end to the beams and at the opposite end to the derrick-post A. Tothe post A are suitably hinged supporting-wings G, of any preferredconstruction, or similar to those shown in the patent above referred toand for the same purposeviz., to form a supportingbase to steady thederrick-post when the wings are brought out at right angles to thebeams; and when the machine is not in use the wings may be folded backagainst one of the beams c and its brace.

By the employment of two supporting-wings and two supporting-beams, c, Iam enabled to brace and support the derrick-post on its four sides.Besides, the post in the presentinstance has connected to it thecross-head B, which further steadies the post to render it firm andstationary.

The supporting-beams c are pivoted to the runners b, so as to allow ofthe derrick or frame of the machine being adjusted to adapt it to unevenground upon which it rests, by first loosening the brace or braces d attheir lower ends and raising or lowering the supporting-beams asrequired, and afterward attaching the braces. to the beams in theiradjusted position.

The upper end of the post A has pivotally connected to it a metal cap,D, as shown more clearly in Fig. 4, which supports the operating partsof the machine. The upper portion of the cap D has a plate, 6,extendingforward, and has a slot through which passes a curved metalbar, E, pivoted at its lower end, as shown at f, the purpose of whichwill be hereinafter described.

To the metal cap D is pivoted a beam, F, which preferably consists ofparallel bars connected together by transverse braces and strengthenedby wire braces connected to the sides of the bars, the bars beinglocated upon the sides of the metal cap, so as to steady it. i

The pivoted cap D and the beam F, pivoted thereto, enable the operatingparts of the elevator to be raised or lowered and also moved to theright or left in a horizontal direction,

(as in my former patent,) in order to deposit the loadat the placerequired.

The beam F is provided at its rear end with a suitable weight, G, forthe purpose ofbalancing the beam F and assisting the horse in raisingthe load.

To the sides of the beam F are pivoted the rear or inner ends of arms H,which extend outwardly at an angle'as they project forward, and haveconnected to them, by pivots t, a rake-head, I, provided with straightteeth h, the cross-bar of the head, as shownat t, being connected to theteeth by wire braces 7s. A cord or rope, Z, has one end connected to across-brace of the arms H, as shown at Z, saidrope passing around pulleyin upon the crossbar 1', thence extends rearwardly and passes aroundpulley 0, secured to one end of ashort ICO cord or rope, p, the oppositeend of said cord or rope being attached to the curved metal bar E. Bymeans of this cord or rope Z the two sets of teeth are operated, as willbe presently described.

The beam F is raised or lowered by the cord or-rope n, which passesaround a suitable arrangement of pulleys connected to the rear end ofthe beam and to the post A.

The armsH are braced by wires r,connected thereto and to the beam. F,said arms forming a support for the grabbing device, as well as greatlystrengthening the machine over the single arm shown in my former patent.

The cross-bar t and wire braces is form together a platform for the hayor other loose substance being elevated, and as an auxiliary to theteeth It, I provide the curved teeth 8, secured to the cross-head t,which is pivoted to the arms a, projecting from the crossbar z, saidteeth being used as grab-teeth to hold the hay upon the straight teethh.

In operation, the grabbing device, consisting of the two sets of teeth,is lowered to the desired position by means of the cord or'rope n, andthe hay placed on the straight teeth h, after which the curved wireteeth 8 are brought down on the load to hold the hay on the teeth h,and, with its load, the device is elevated by means of the cord or ropen, which raises the front end of the beam F, and with it the arms II.While this is being done the cord or rope I should be pulled down upon,in order to keep the teeth 8 down against the hay, and also prevent therake-head I from tipping and accidentally discharging its load. By meansofthe cord or rope I and cord or rope connected to the curved metal barE, the teeth 8 are retained in a level position when the load is beingelevated.

It will be noticed that when the several operating parts of the device,with the load, are being elevated they will at the same time swingaround, the metal cap turning on the end of the post A.

To avoid the necessity of pulling on the cord or rope Z when elevatingthe load, the cord or rope is kept taut by fastening it to the 7 side ofone of the arms H, a ring, 12, being provided for this purpose to hookonto a pin,

.10, as shown in Fig. 1.

When the device is swung around to the place where the load is to bedeposited, the cord or ropel is released, which will allow the tiltingrake-head I to discharge its load; and atthe same time this is done theteeth 8 are raised and held in such position by a spring-latch, K,engaging with the keeper L, a guide-rod, 00,

being employed to insure thelatch and keeper engaging with each other.

Any suitablelatch device may be substituted for that shown, so long asit will serve the purpose of holding the teeth 8 in an elevated positionwhile the load is being taken on the teeth h and when being discharged.

I do not desire to be understood as confining myself to the preciseconstruction of the various parts, as it is evident that many changesmaybe made that would come within ordinary mechanical skill and judgment,and such changes I reserve the right to make without departing from theprinciple of my invention.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a hay-elevator. the post A, provided with the pivoted cap D,having slotted plate 6, in combination with the curved metal bar E,extending up through the slot, the cord or rope 1), attached to the barand provided with a pulley, 0, and the cord or rope I, and the teeth 8,connected to a suitable pivoted head, to which the latter-mentioned cordor rope is attached, substantially as and for the purpose set forth.

2. In a hay-elevator, the pivoted rake-head I, having straight teeth h,in combination with the cross-head t, pivoted to the support of theteeth It and provided with curved teeth a, and a latch device forholding said head and teeth elevated, substantially as and for thepurpose specified.

3. In a hay-elevator, the tilting and swing ing beam F, provided withweight G, in combination with the arms H, pivoted to said beam andcarrying the grabbing device, and braces 1", connecting the beam andarms and operating substantially as and for the purpose set forth.

4. In a hay-elevator, the post A, provided with the metal cap D, havingslotted plate 0 extending beyond the side thereof, combined with the barE, pivoted atf and extending up through the slot of said plate, the armsH, the grabbing device carried by said arms, and the rope connectingsaid arms with the bar E, all substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

PETER F. FLEMING.
